- -> > For you guys running in the 5-liter classes, an Aussie 302 crank in
- -> a >351C block could give you a huge advantage over the Windsors.
- ->
- -> Can I assume they don't do this already? What about weight? Isn't the
- -> 351C block a lot heavier?
-
- Are you kidding? Very, very few Americans even know of the existence
- of the 302C. Anything from Australia might as well be from Mars.
-
- Yes, the 351C block is a little heavier, but it's within five pounds of
- the Generic Motors Chevrolet, and the longer rods and bigger bearings
- are well worth it.
-
-
- -> the same - makes life hard when you need to tell at a glance what the
- -> capacity is. Trust me on this, but the 302 loves to rev its head off,
-
- Is there any difference on the crank flange at the flywheel? How about
- the harmonic balancer? Not that you can see either very well while the
- engine is in the car.
-
-
- -> Anyway, I have a query. I have been told that the 351 motors produced
- -> here were more 4 bolt mains than 2 bolt mains. From about 1975 on, we
- -> produced 2 bolt only and imported the 4V 4 bolt mains 11:1 motor from
- -> the US. What was this motor, was it a 351C?
-
- According to my Ford stuff, all US 351Cs were cast in Cleveland, Ohio.
- For a few years, they were shipped to Ford Australia for machining, then
- shipped back to the USA. Wierd. Anyway, Ford USA canned the motor in
- 1974 after a five year production run. Your post-'75 US four bolts were
- probably shipped out of existing inventory.
-
- You might be interested to know that Ford's Muscle Parts and
- Off-Highway Operations in the early '70s sold Aussie four bolt blocks at
- super-premium prices - close to the cost of a complete US motor, just
- for the block! The Aussie blocks were a better grade of cast iron, and
- were thicker wall construction, probably because Australians didn't see
- any point trying to cast sheet metal. The US 351Cs had some flimsy
- areas... like the cylinder walls. <sigh>
-
- The early Falcons used 351 Windsor motors, but I have no certain
- information as to where they're from. I tend to think they were
- imported from the US, since Ford Oz was so proud of their 351C.
-
- Incidentally, the 351W came out in late 1968 here in the US. The BOSS
- 302 and 351C came out in '69. The Ford information I have indicates the
- BOSS 302 was designed by Ford for Trans Am racing, and the heads were
- adapted to the Mercury-designed 351 Cleveland. I've never been sure
- exactly *why* Mercury wanted their own motor, or why they disowned it so
- rapidly. It would have been much more reasonable to put the BOSS heads
- on the 351W, like the common B&A conversion here. Ah, well...
-
-
- -> produced 2 bolt only and imported the 4V 4 bolt mains 11:1 motor from
- -> the US. What was this motor, was it a 351C?
-
- Four bolt, four barrel 11:1, hydraulic lifter - that's the 1969-1970
- standard 4V motor. For solid lifter, it'd be the BOSS 351. For solid
- lifter, 8:1 compression, it'd be the 351 HO. Both were made only one
- year, available in the Mustang only, and are rather rare.
-
-
- -> lbs (1568 Kg), hey? Boy those were the days. Now we get this 5.0L
- -> Windsor (made in Mexico?) and fair dinkum, it would have trouble
-
- I've heard the Mexico rumor before, but nothing to authenticate it.
- I'd kind of like to know if it's true, because the Mexican Chevys are
- nothing you'd want to trust. Up here, people think a "5.0" is a monster
- motor. <sigh> We all know, of course, you must have at least seven
- liters to pound your chest and rattle your cage... but compared to a
- 1600, I guess a 5.0 does look impressive.
